Electrons in the tube are controlled by the constant magnetic field and the constant electric field perpendicular to each other, interact with high-frequency electromagnetic field, convert the energy obtained from the constant electric field into microwave energy, so as to achieve the purpose of generating microwave energy. The magnetron has the characteristics of high power, high efficiency, low working voltage, small size, light weight and low cost.

[0003] The tube core of the magnetron usually includes an anode assembly, a cathode assembly and an exhaust pipe assembly. In order to ensure the mutual perpendicularity of the constant magnetic field and the constant electric field, the cylinder body of the anode assembly needs to be coaxially arranged with the pipe body of the cathode assembly. The concentricity and vacuum degree of each assembly are important indicators for determining whether the magnetron is qualified. In the anode assembly, the anode plates need to be arranged radially along the central axis in the internal space of the anode cylinder, thereby forming a resonant cavity. The position accuracy of the anode plates in the internal space of the anode cylinder will seriously affect the energy coupling and power output of the magnetron.

DETAILED DESCRIPTION

[0042] To make the above-mentioned purposes, technical solutions and advantages of the present application more clear and easy to understand, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments of the present application described herein are only part of the embodiments of the present application, which are only used to explain the present application and do not constitute a limitation on the present application. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] Embodiment 1

[0044] As Figures 1-5 The present application provides a correction tool for an anode cylinder assembly, which comprises a correction table 3, a correction device 4 and a correction die 5 fixed on the correction table 3, the correction device 4 is used to cooperate with the correction die 5 to correct the assembly accuracy of the anode cylinder assembly 1, the correction table 3 is movably connected with a first grabbing device 6 which makes a reciprocating motion on the correction table 3, the first grabbing device 6 is used to grab at least two anode cylinder assemblies 1 at a time, after one of the anode cylinder assemblies 1 is grabbed away from the correction die 5, the other anode cylinder assembly 1 is placed on the correction die 5.

[0045] Specifically, as Figure 1 shown, at the beginning of the production and assembly of the anode assembly, a plurality of anode plates 101 are clamped in a radial manner at equal distances and coaxially to form an anode plate assembly 102; while the anode plate assembly 102 is assembled into the anode cylinder 103, the center pin 104 is also pressed into the axis of the anode plate assembly 102, so that the center pin 104 presses the anode plate assembly 102 and the inner circumferential surface of the anode cylinder 103 tightly, thereby forming the anode cylinder assembly 1. After the two ends of the anode cylinder assembly 1 are pressed into the size-adjusting ring 2, they will enter the subsequent assembly process. The whole process of the production and assembly of the anode assembly, including the subsequent assembly process, can be automatically produced and assembled by using a flow production line.

[0046] In the automatic production and assembly process of the anode assembly, the center pin 104 will be knocked out of the anode assembly from the self-adjusting ring process until the upper die, brazing and die removal processes. Before the pressing ring process of the anode cylinder assembly 1, the assembly accuracy of the anode cylinder assembly 1 itself, i.e. the initial assembly accuracy of the plurality of anode plates 101 in the internal space of the anode cylinder 103, will undoubtedly directly affect the yield rate of the anode assembly and the stable operation of the automatic flow production line.

[0047] Through the correction tool for the anode cylinder assembly, no matter how the assembly accuracy of the plurality of anode plates 101 is after being pressed tightly with the center pin 104 into the anode cylinder 103 at the beginning of the production and assembly of the anode assembly, the anode cylinder assembly 1 still needs to be placed on the correction die 5 by the first grabbing device 6 after being preliminarily formed by the above-mentioned process, and the assembly accuracy of the anode cylinder assembly 1 is corrected by the correction device 4 cooperating with the correction die 5, i.e. the relative positions between the assembly units after the pre-pressing (herein the pressing action of the anode cylinder assembly 1 in the above-mentioned preliminary forming process can be called pre-pressing) and the pre-pressing effect are standardized and corrected.

[0048] Since the clamping accuracy exists when the plurality of anode plates 101 are radially clamped before pre-clamping, the relative position accuracy exists when each assembly unit is in place after pre-clamping, and the above-mentioned accuracy is relatively difficult to control accurately, and the assembly accuracy or pre-pressing effect after pre-clamping is based on the accurate control of the above-mentioned accuracy. By adding a standardized correction after pre-pressing, the assembly accuracy of the anode plate after automatic assembly is improved, the good product rate of the anode assembly is ensured, and at least the stability of the automatic assembly line is met in terms of assembly accuracy.

[0049] In addition, in terms of programmed response of the automatic assembly line, the first grabbing device 6 makes a cyclic reciprocating motion on the correction table 3. In each cyclic reciprocating motion, the first grabbing device 6 will first grab at least two anode cylinder assemblies 1 at a time, and after one of the anode cylinder assemblies 1 is grabbed away from the correction mold 5, the other anode cylinder assembly 1 is placed on the correction mold 5, and then the first grabbing device 6 is reset to re-cycle the above-mentioned reciprocating motion, thereby realizing the programmed response of the automatic assembly line in terms of grabbing-placing-correction-grabbing away. Thus, the stability of the automatic assembly line is met in terms of assembly accuracy and programmed response.

[0050] Preferably, the correction device 4 is a downward pressing type, which includes a downward pressing part 41 matched with the anode cylinder assembly 1, and the correction mold 5 includes a clamping seat 51 matched with the anode cylinder assembly 1, wherein the matching means that the lower end of the anode cylinder assembly 1 can be placed in the outer edge of the clamping seat 51, and the downward pressing part 41 can be placed in the inner edge of the upper end of the anode cylinder assembly 1.

[0051] Specifically, the "sleeving-pressing" correction method can greatly simplify the structure of the correction device and facilitate the realization of fast, streamlined and standardized correction. More specifically:

[0052] The clamping seat 51 is in a cylindrical shape and has a diameter smaller than the inner diameter of the anode cylinder assembly 1. The clamping seat 51 includes a first fan-shaped column 511 and a first clamping plate 512 arranged in a staggered manner on the side of the clamping seat 51. The first fan-shaped column 511 and the first clamping plate 512 form a first central groove 513 in the center of the clamping seat 51. The height of the first fan-shaped column 511 is higher than that of the first clamping plate 512, thereby forming a first clamping groove 514. The upper end of the first fan-shaped column 511 is provided with a first smooth inward arc 515.

[0053] The lower pressing part 41 is in a cylindrical shape and has a diameter smaller than the inner diameter of the anode cylinder assembly 1. The lower pressing part 41 comprises second fan-shaped columns arranged in a staggered manner on the periphery of the lower pressing part 41 and second clamping plates. The second fan-shaped columns and the second clamping plates enclose a second central groove in the center of the lower pressing part 41. The height of the second fan-shaped columns is higher than that of the second clamping plates, thereby forming a second clamping groove. The lower end of each second fan-shaped column is provided with a second smooth inward arc.

[0054] As another preferred embodiment of the present application, the clamping seat 51 comprises first fan-shaped columns 511 arranged in a staggered manner on the periphery of the clamping seat 51 and first clamping grooves 514. The lower pressing part 41 comprises second fan-shaped columns and second clamping grooves arranged in a staggered manner on the periphery of the lower pressing part 41. That is, the first clamping plates 512 and the second clamping plates can be provided by default, or the first clamping plates 512 can be integrally formed with the first fan-shaped columns 511, and the second clamping plates can be integrally formed with the second fan-shaped columns.

[0055] Therefore, when the correction device 4 performs the correction operation, the upper and lower ends of the anode cylinder 103 can be respectively sleeved with the lower end periphery of the second fan-shaped column and the upper end periphery of the first fan-shaped column 511, the upper and lower ends of the center pin 104 can be respectively abutted and accommodated in the second central groove and the first central groove 513, and the upper and lower ends of the plurality of anode plates 101 can be respectively abutted and accommodated in the second clamping groove and the first clamping groove 514. When the correction device 4 performs the assembly precision correction on the anode cylinder assembly 1 in cooperation with the correction mold 5 according to the "sleeving-pressing" correction mode, the relative positions between the assembly units and the pre-pressing effect can be quickly standardized and corrected under the joint action of the lower pressing part 41 and the clamping seat 51, that is, the formal pressing is further completed. The above-mentioned arrangement of the lower pressing part 41 and the clamping seat 51 can greatly simplify the structure of the correction device and is conducive to realizing the rapidity, flow, and standardization of the correction.

[0056] Preferably, the lower pressing part 41 is suspended above the correction mold 5 to perform vertical reciprocating motion.

[0057] Specifically, when the correction device 4 performs the assembly precision correction on the anode cylinder assembly 1 in cooperation with the correction mold 5 according to the "sleeving-pressing" correction mode, the lower pressing part 41 further adopts the vertical reciprocating pressing mode, which can further simplify the structure of the correction device and realize the rapidity and stability during the correction. More specifically:

[0058] The correction device 4 comprises a supporting leg 42, a top plate 43, and the lower pressing part 41. The lower end of the supporting leg 42 is fixedly arranged on the correction table 3, and the upper end of the supporting leg 42 is fixedly supported by the top plate 43. The lower pressing part 41 is suspended below the top plate 43 to perform vertical reciprocating motion.

[0059] The correction mold 5 further comprises a base 52 integrally formed or fixedly connected with the correction table 3 below the clamping seat 51, the base 52 is cylindrical and concentrically arranged with the clamping seat 51, the radial diameter of the base 52 is greater than that of the clamping seat 51, and the base 52 is integrally formed with at least the first fan-shaped column 511.

[0060] Preferably, the first grabbing device 6 has three mechanical hands for grabbing three anode cylinder assemblies 1, and the correction table 3 is fixedly provided with a pre-embedding mold 7 on the side of the input end of the correction device 4, the pre-embedding mold 7 has the same structure and shape as the correction mold 4.

[0061] Specifically, in the automatic flow production line, the anode cylinder assembly 1 after preliminary forming is conveyed to the position after the previous automatic flow line process, the first grabbing device 6 continuously grabs the anode cylinder assembly 1 to be corrected from the conveying position 31 on the correction table 3 through the cyclic reciprocating motion and completes the conveying and placing to the correction mold 5, then the correction device 4 continuously performs precision correction on the anode cylinder assembly 1 through the continuous vertical reciprocating motion to match the correction mold 5, after the precision correction is completed, the first grabbing device 6 can grab the corrected anode cylinder assembly 1 from the correction mold 5 and place it on the output end side of the correction device 4, so as to facilitate the anode cylinder assembly 1 to enter the next automatic flow line process, and the place where the anode cylinder assembly 1 is grabbed and placed can be correspondingly referred to as the "output position 32".

[0062] Of course, those skilled in the art can understand here that after the accuracy correction is completed, the corrected anode cylinder assembly 1 can also be grabbed off from the correction mold 5 by other grabbing devices and placed at the output position 32. However, the problem caused thereby is that the other grabbing devices not only need to form a movement avoidance to the lower pressing part 41 when performing the grabbing-off and placing operation on the anode cylinder assembly 1, but also need to form a movement avoidance to the first grabbing device 6. Since the anode cylinder assembly 1 itself is relatively precise, the correction mold 5 is also relatively precise, and the stroke of the vertical reciprocating movement of the lower pressing part 41 and the stroke of the cyclic reciprocating movement of the first grabbing device 6 are not very large, and in order to ensure the good connection of each movement unit in the automatic assembly line, the structure design of the correction tooling is too complex. Through the setting of the first grabbing device 6 having three mechanical hands and the setting of the pre-placing mold 7, the first grabbing device 6 can uniformly grab off the anode cylinder assembly 1 from the correction mold 5 and place it at the output position 32, so as to overcome the defect that the structure design of the correction tooling is too complex; at the same time, through the segmented cooperative grabbing and grabbing-off operation, the cyclic reciprocating movement stroke of each mechanical hand of the first grabbing device 6 is reduced, thereby further improving the precise control of the first grabbing device 6. Those skilled in the art can understand here that for any one of the mechanical hands, the movement trajectory of the mechanical hand with the first grabbing device 6 cyclic reciprocating movement is shown in the accompanying drawings, and since the clamping and releasing actions of the mechanical hand are easy to understand, the accompanying drawings do not contain the movement trajectory of the clamping and releasing actions of the mechanical hand itself here. Figure 5 Figure 5 The movement trajectory of the clamping and releasing actions of the mechanical hand itself is not contained in the accompanying drawings here.

[0063] Preferably, the mechanical hand provided at one end of the first grabbing device 6 in the direction away from the correction device 4 is a first mechanical hand 61, the first grabbing device 6 is driven by a gas cylinder 64, and the gas cylinder 64 is fixedly provided at the upper end of the first mechanical hand 61.

[0064] Specifically, the gas cylinder 64 is used to drive the whole first grabbing device 6, and the three mechanical hands cyclically reciprocate together under the action of the gas cylinder 64, and in the cyclic reciprocating movement process, the three mechanical hands can simultaneously perform clamping or releasing actions, or when the first mechanical hand 61 is upward and downward grabbing and the other mechanical hands are forward and backward grabbing, the first mechanical hand 61 and the other mechanical hands can also perform clamping or releasing actions in sequence, but even if it is performed in sequence, the interval time is very short. The use of only one gas cylinder 64 to drive the synchronous action of the three mechanical hands can further simplify the structure design of the first grabbing device 6, and since the stroke of the first mechanical hand 61 or the gas cylinder 64 is always between the conveying position 31 and the pre-placing mold 7, the gas cylinder 64 will not touch the top plate 43, thereby further facilitating the selection and structure design of the driving device of the first grabbing device 6. ​

[0065] Preferably, the first grabbing device 6 further comprises a second mechanical arm 62 and a third mechanical arm 63 arranged in sequence away from the first mechanical arm 61, the first mechanical arm 61 being an up-down type grabbing, and the second mechanical arm 62 and the third mechanical arm 63 being a front-back type grabbing.

[0066] Specifically, in the automatic flow production line, the anode cylinder assembly 1 to be corrected at the conveying position 31 is usually arranged in a linear type to meet the needs of continuous operation, so that the programmed response of the next process can be considered, and the cost of the automatic production line is saved. At this time, the first mechanical arm 61 cannot adopt the front-back type grabbing mode, but it can adopt the up-down type grabbing, and then the anode cylinder assembly 1 after the pre-placing mold 7 can be grabbed by the second mechanical arm 62 and the third mechanical arm 63 through the transformation of the pre-placing mold 7.

[0067] Preferably, the correction table 3 is fixedly arranged at the output side of the correction device 4, and a mobile mold assembly that makes a circular reciprocating motion on the correction table 3 is movably connected to the correction table 3, and the mobile mold assembly comprises a first mobile mold and a second mobile mold. The first mobile mold and the second mobile mold receive the anode cylinder assembly 1 grabbed away from the output position 32 by the first grabbing device 6 in an interleaved motion manner during the circular reciprocating motion of the mobile mold assembly.

[0068] Specifically, those skilled in the art can understand here that the anode cylinder assembly 1 at the output position 32 is placed by the third mechanical arm 63. When the next automatic flow line process needs to grab the anode cylinder assembly 1 in pairs due to the processing process, the first mobile mold and the second mobile mold receive the anode cylinder assembly 1 grabbed away from the output position 32 in an interleaved motion manner during the circular reciprocating motion of the mobile mold assembly, and then other grabbing devices grab the two anode cylinder assemblies 1 on the mobile mold assembly at the same time to the next automatic flow line process, thereby further meeting the multi-scenario application requirements of the next automatic flow line process. More specifically, the interleaved motion manner is:

[0069] The first mobile mold and the second mobile mold can move synchronously at the same speed, or one of them can move alone and push the other to move synchronously when the first mobile mold and the second mobile mold are in a close state, so that the interval between the two is relatively fixed within a period of time.

[0070] The first moving mold and the second moving mold can also move synchronously but at different speeds, or the first moving mold and the second moving mold can also move independently, so that the interval between the two is relatively variable in another period of time.

[0071] It should also be noted that the moving mold assembly, or the first moving mold and the second moving mold, needs to be provided with a driving device, which realizes the above-mentioned staggered movement mode under the action of the driving device, thereby realizing the technical effect that "other grabbing devices can simultaneously grab the two anode cylinder assemblies 1 on the moving mold assembly to the next automatic assembly line process". The driving control method involved is predictable by those skilled in the art, and will not be described here.

[0072] Preferably, the correction tool is integrally arranged on the opposite side in a paired arrangement.

[0073] Specifically, on the correction table 3, the correction device 4 can be provided with two groups of downward pressing parts 41 on both sides of the correction table 3, and correspondingly, the correction mold 5 also has two groups, and the pre-placed mold 7 can also have two groups, and the first grabbing device 6 can also have six mechanical hands, so that the correction device 4 can simultaneously receive and output two groups of anode cylinder assemblies 1. Further, the moving mold assembly can also have two groups, so that four anode cylinder assemblies 1 can be simultaneously grabbed into the next automatic assembly line process.
